Well I finally finished it off for the project i have on the side, the map is as accurate to the real thing as i could get, little differences in terrain height will be added as i actually build cardiff in-game, but all in all, i think it's pretty damn accurate considering most of it was hand terraformed, painstakingly tile by tile (there are over 160). Let the games begin!
